'70 [1.77, whom it may concern:

Be it known that I, NATHANIEL Arron, a citizen of the United States, anda resident of Sandy Lake, in the county of Mercer and State ofPennsylvania, have invented certain new and, useful Improvements inlVeather-Strips; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective view of thelower portion of a door-frame and door provided with my improvedweather-strip, showing the door open. Fig. 2 is afront View of the same,showing the door closed and a portion of the lower end of the doorbroken away. Fig. 3 is a vertical sectional view of the strip, showingthe arm of the strip and the catch upon the jamb in engagement, andshowing the door and jamb in dotted lines. Fig. 4 is a detail view ofthe catch upon the jamlo, and Fig. 5 is a sectional view taken on theline m x of Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of weather-strips which arehinged to the lower edge of the door and have springs for raising theirfree edges when the door is opened, and means for automatically tiltingthe free edges of the strips against the floor when the dooris closed;and it consists in the improved construction and combination of parts ofthe same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the door. B is thesill, and O G are the jambs of the door-frame. The lower edge of thedoor has a recess, D, extending the en tire length of the lower edge,and this recess has in its bottom another recess or groove, E, and theside edge of the door has a sector-- shaped recess, F, at its lower end,the said recess having the center ,of the sectorat the corner toward thejamb. The inner side of the recess in the lower edge of the door or theside toward the door-jamb has staples G G, in which a rod, H, isjournaled, which rod has at one end an arm, I, bent at a right angle tothe rod, and rocking in the sectorshaped recess in the edge of the door.A longitudinally doubled strip, J, of sheet metal, is secured at itsdoubled edge to this red, and a strip, K, of rubber or other similarflexible material, is clamped between the flanges of the metallic stripand firmly retained between the same.

A spring rod, L, is secured at one end in the groove in the lower edgeof the door, and is secured near its middle by a staple, M, while itsother end is secured to the upper side of the metallic strip, so thatthesaid spring-rod will serve to draw the metallic strip and its rubberstrip up into the recess in the lower edge of the door, the spring-rodresting in the groove in the recess.

A plate, N, is secured upon the jarnb of the door, having a verticalslot, 0, sliding upon a screw, P, in the jamb, and this plate has itsinner edge provided with a bent flange, Q, which bears against the beadof the door, and which flange serves to keep the plate in its verticalposition, while the lower outer corner of the plate is cut off obliquelyand provided with an oblique flange, R.

YVhen the door is closed, the arm of the rocking weather-strip willstrike the inclined flange and be tilted into a horizontal position, ornearly so, bringing the edge of the elastic strip to bear against thesill of the door, and when the door now is opened the arm will bereleased, and the springrod will draw the weather-strip up into therecess in the lower edge of the door. The plate upon the jamb beingprovided with a vertical slot with which it slides upon theadjusting-screw, may be ad justed upon the said screw at any desiredheight, and as the elastic strip wears out the plate may be lowered, thearm beingtilted closer to the horizontal position as the plate is movedcloser to the sill. The vertical flange upon the plate, bearing againstthe bead of the door-jamlo or against the abutment upon the said jainb,will serve to keep the plate in its proper position and prevent it frombeing tilted when the arm strikes it, so that the arm will be tilted toits proper angle and the weather-strip be forced against the sill withsufficient force to exclude water or air, but not with sufficient forceto destroy the rubber strip.

The plate may be on either jamb, and the arm of the weather-strip mayproject either at the latch edge of the door, as shown in the drawings,or at the hinge edge, the operation of the device being the same; but Iprefer to have the arm upon the latch end of the door and the plateconsequently upon the latch jamb, inasmuch as the arm will almost beforced directly in upon the plate when the arm is upon the hinge end ofthe door.

I am aware that it is not new to construct weatherstrips consisting of alongitudinal strip hinged in a recess in the bottom part of the door andoperated by means of an attachment secured to'theside of the jamb ofthedoor. and I do not claim such construction, broadly; but

I claim and desire to secure by Letters Patent of the United States- 1.The combination, with a door having a grooved recess across its bottom,of a rod pivoted in said recess, a longitudinal folded strip secured atits doubled edge around said rod, and having an elastic strip clampedbetween its outer edges, a spring-rod secured in the groove of therecess and to the strip, the outer end of said hinge-rod being bent atan angle and moved in a sector-shaped recess in the edge of the door,and an inclined stop secured to the side of the jamb of the door against0 which the bent end of. said rod operates, as shown and described.

2. The combination of a door having a recess in its lower edge formedwith a groove, and having a sector-shaped recess in the lower end of oneedge, a rod rocking in staples in the inner side of the recess, andhaving an arm at one end rocking in the sector-shaped recess, alongitudinally-doubled metallic strip secured at its doubled edge to therod, and having an elastic strip clamped between its flanges, aspring-rod secured in the groove of the recess and to the strip, and aplatehaving a vertical slot and a vertical flange bearing against theabutment. of the jamb and an oblique flange at its lower outer corner,the said plate sliding adjustably upon a screw entering the door-jamb,as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

NATHANIEL AMON.
